'PC Controlled PIC Project Question'

PICListers,
I am attempting to control a PIC16C65 via RS232. I have all the details of the R
S232 connection completed but have a question on the PC program I need. I want t
o have three different possible selections which are made via user through PC. A
fter selection is made the PIC does what it is programmed to do. Question: What
language should I write the user interface in?? I've never done this before, (tr
ied to control something via PC) and I am not sure where to start. Should it, or
can it be done by either QBASIC or C?? What about ProComm Plus?? Any suggestion
s would be of great help!!!!! Thanks in advance!!!

                       Best regards,
                       Steven

Re-write the PIC code so that all commands can be driven from the
keyboard using any terminal program.
I have done this on many occasions. See:
http://www.dontronics.com/picex.html

Also see: http://www.wirz.com
Myke/Ben have done the SLI-OEM the same way.

OK, your application menu may be fairly basic, but by doing this,
instant control is available from virtually any system/language and
users can knock a control program together with full understanding of
the requirements.

Communicating through the parallel port on I2C bus. I am having a bit of a
problem with timing ;)... anyone got a DSO I can borrow ??

Procomm script files are great if you or others with Procomm will be the
end-users of this software.  A decent GUI with precise RS232 control is what
Procomm does best, and if you're familiar with the scripting language you
can have something menu driven working in under an hour.  If you are new to
the language, allow a day or so.

If you plan to sell this product or distribute it to a whole wack of people
(like over 10) then I wouldn't mess with Procomm other than for development.
Management of the script versions and requiring everyone to have a certain
version of Procomm gets awkward.

Also, be aware that the old version of Procomm for DOS does sustained 38,400
baud transfers on a mere 16MHz 286, while the latest Procomm for Windoze
running under a 450 MHz Pentium II won't be able to keep up.  I love my
Procomm for DOS as it's nice & basic, and does every thing I need it to do,
very reliably.  The DOS version also supports all the CTRL- keys for
transmitting the non-printable ASCII characters, I don't think the Windows
version does this.

Hi,

if your task is only to choose one from three possible selections, I
suggest Procomm Plus. You can manage this simple task with its scripting
language.

If your problem is rather complex, I suggest the Micro-C for PC from Dave
Dunfield (http://www.dunfield.com). I personally use it with success. It has a
built-in interrupt-driven serial communication interface. Better yet, it
has menuing and windowing environment, and it is pretty bug-free. For $25
is a true bargain. The only minus it does not support floating-point
numbers.

I hope this helps.

Imre

I've done it a number of times as well (as Don pointed out) - it really
makes things easier for debugging (ie you can debug the PIC and then the PC).

Personally, I like using Hyperterminal (on Windows/95/98), but recently,
I've discovered that Hyperterminal works differently on Windows/98 than on
Windows/95/NT (3.5).  This is a problem with the YAP/Emu that I'm trying to
resolve right now (sigh).

You can use either QBASIC or C, but you might also want to take a look at
Jan Axelson's "Serial Port Complete" and write it in Visual Basic - It's
actually pretty easy and you end up with a Windows I/F and VB is probably
easier to learn than C.  The book is available from her for 10% for one more
day.
